Thanks !
I had a problem with BaseX 7.6 : something strange, where child nodes seemed to be returned in a different order with something like $node/node().
When I tried to display $node, the order of the children were correct, but when I tried to display $node/node(), it was different.
But finally, i updated to BaseX 7.7.2 and now it works fine as expected.

But thanks for your feedback !

Hi Wendell (cc @basex-talk),

thanks for your mail. Yes, there are cases in which the result of an
axis step are not returned in document order. One such example is
shown as follows:

Document Order:
<A>
  <B><c/></B>
  <c/>
</A>//c / parent::node()

No document order (when using the map operator):
<A>
  <B><c/></B>
  <c/>
</A>//c ! parent::node()

I was using parent::node() instead of child::node() here, but the
example can surely be adapted to also include a child step.

Hope this helps?
Christian
